The iaiiieeCi--guiee are in theform of levers '95 i3, Wiiioi'i eie hungizo e pin i4, carried by the opper ende ofvioms l5, Whioh are secured ettheir lower ends to e shaft or spindle 16, momiiae eo es to be free toturn in Suitablev bearings on the bemlzxfce l, each of the bars xoo 15having a projecting arm 17, and these arms carrying a shaft 18, to whichis secured a pattern-drum 19 and a ratchet-Wheel 20, the pat tern-dro mhaving pins or other pattern-surfaces adapted to act upon the outer endsof the levers 13, so that the inner or thread-gnid ing end of any one ofthe levers may be depressedA in order to feed its thread to the needlesat the knitting-point or may be elevated so as to direct its thread overthe tops of said needles.

The desired movement of the pattern-drum 19 is elected in thevfollowingmanner: 0n the shaft is an eccentric 21, and the sleeve of thiseccentric carries apawl 22, yvhh engages with a ratchet-Wheel 23 on thehub of a pattern 4- chain wheel 24, said hub being mounted sor as to befree to turn 'on the shaft or spindle 16. Also mounted so as to be freeto turn on said shaft 16, but connected so as to have no movementindependent of each other, are apair offarms 25 and 26, the arm 25projecting into the path of anv antifriction-roller 27, carried by theback of the bevel-pinion 4, and a spring 28 acting on the arm 26 inorder to move the arm 25 into range of said antifriction -roller. Thearm 26 is forked and' carries a hooked pawl 29, which is acted upon byaspring 30, so that its hooked end tends to move into engagement with theteeth of the ratchet-wheel 20. Projecting forwardly from the arm 26,however, is a iinger, ,ewhich isnormally in contact with therednoedcentral portion of a stop-lug 32, the lattenheine, pivoted, by means ofa pin 33, to one of the bars and being of such Vlength as to projectover the pattern-chain 34,wlii ch is mounted upon and actuated by thepattern- Wheel r24:.- Normally, thereforethat is t0 say, when the partsare in the position shown Xin Figs. 1 and 2-the arm 26 is prevented frommoving forwardly, so as to cause its pawl 29 to engage with the teeth ofthe ratchet 2O;1b but-when the stop-lng 32 is lifted by the action ofany one of a number of projections 35 on the pattern-chain 84 the finger81 will be released from the restraining inlinence of said stop-lug andthe arm 26 Will be at liberty to swing forwardly under'the action of thespring 28, so that its pawl 29 willl engage with a tooth of theratcl1et-wheel20, and upon the backward movement of said arm 26, causedby the action of the antifriction-roller 27 on the arm 25, said pawlwill move the ratchet- -pins of the pattern-drum 19, so as to move thewheel to theextent of one tooth and will thereby edect a change in theposition of the operative thread-guiding lever into inopen' -ativeposition and move an inoperative threadguiding lever into operativeposition,ti1e stoplng 32 dropping in front of the finger 31 as soon asthe support of the projection is removed, so as to retain the parts inoperative relation to each other until further change in the position ofthe thread-guides is desired.

Secured to the projecting end of the shaft or spindle 1G is ahandle 36,by means of which said shaft may be partiallytnrned in its bear,- i'ngs,seas to cause the bars l5, with the'levers 13 yand other partsearriedthereby,to be 7o swung away from the needle-cylinder, in order topermit of the removal of said cylinder from the machine and theinsertion of a new cylinder in its place.

A rWeighted arm, such as shown by dotted 75 lines in Fig. 2, or someother, available form of retainer may be employed for holding the bars15 andthe parts carried thereby in op erative relation with theneedle-cylinder.

Various means of mounting .the thread. 8c

et We have illustrated one such modification 85 in which thethreadguiding leversl 153il are hung to a' pin 14:, carried by a forkedframe 3*/,which has pins 38, adapted tobearings in fixed standards orbrackets 39 on thefhedu plate 1, said'frame also carrying the shatter 9ospindle otlthe pattern-drum 19S and having a handle 41, lwhereby it maybe conveniently raised or lowered, so as to carry the thread-guides fromor. toward the'needle-cylinder.

In order to prevent the threads running'.

from those gu ldes which are outof action from. catching upon theneedles, we use a needle shield or guard consisting of a bent plate 45,

which incloses the needles on each 'side of the rec point at which they'arel raised l by the knit-` tinivcams in order to'receive. theknittingthread, said bent plate le5 being clit away at .that point', soas to Ipermit threadvte be fed to the needles from any one of 4theguides 13 x05 which is depressed, the thread from the elevated guides,however', asthe needle-cylinder rotates beingso directed by the shieldsor guards v as to'pass over the tops of the raised needles, withwhich'said threadsare no thus prevented from conflitti?,s intoengagement. The shield filas a projecting stem 46,which may be mountedupon the bars 15, as shownl in Figs. land 2, or -npon any other desiredpart of the movable thread-guide carrier, so I I5 as to be moved out ofthe waywith the ythreadguides when it is desired to remove or insert theneedle-cylinder..

Having thus described our invention, we

claim and desire to secure byLetters Patrco ent- 1. The combination in aknitting-machine,- ot a rotatable and removable needle-cylinder, withthread-guides movable into and out of operative relation with' theneedles, and also xav movable from and toward the needles so as topermit of the insertion or removal of the nee- (lle-cylinder.A 2. Aknittingmachine in which are combined n. rotatable and removableneedle-cylinder, thread-guides movable into and out oi operativerelation `with the needles of said cylinder and also movable' to andfrom the needl'ewylinder ecce to permit o the lineen tion and removal ofthe same, and a pattern devioe acting on said thread-guides and movabletoward and from the needle-cylinder With the same. u

3'. A knitting-machine in which are oombined a needle-cylinder, arotatable earrier therefor having a split and tapered ange engaging withthe inner side of the needleeylindor and an annular Wedge rotating withsaid carrier and acting upon the split and tapered iiange of the same.

LA knitting-machine in which are oomll bmed a `needle-Cylinder, arotatable carrier having a split and tapered flange adapted to engagewith the inner side of said cylinder, an annular Wedge engaging withsaid split and tapered flange, and an annular nut engaging with saidannular Wedge. and bearing upon said rotating carrier.

5. A knitting-machine in which are oombined a rotatable and removableneedle-cylinder, a series of thread-guides, a patterndrum for actingthereupon, a pivoted strueture carrying said thread-guides and drum, andoperating mechanism for said patterndrum hung upon the same axis as thecarrier therefor.

U. The combination in a knitting-machine, of a series of thread-guides,a pattern-drum for aeting thereupon, a ratchet-Wheel eonnected to saiddrum, a swinging arm having a pawl for engaging with said ratchet-wheel,a movable stop-lug for arresting the movement ot said pawl-oarrying arm,a pattern- '.ohain for moving said lug, and means for aetnating saidpattern-chain and swinging arm.

7. A knitting-machine in which are com- 7 bined a rotatableneedlecylinder, thread guides movable vertieallyinto and out ofoperative relation with the needles, and a needle shield or guardcovering and protecting the tops ofthe needles on eaeh side of theknitting-point,whereby the thread from a raised guide will pass over`said shield.

8. A knitting-machine in which are oombin ed a rotatable needle-eylinder, threadguides movable -vertically into and out of operativerelation with the needles, and a needle shield or guard covering andprotecting the tops of the needles on each side of the knitting-point,whereby the` thread from a raised guide will pass over said shield, thelatter being out awayso as to escape the needles when the latter rise toreceive the thread from the operative guide.

9. A knitting-machine in which are cornbined a rotatable and removableneedle-cylinder, thread-guides movable vertically into and outofoperative relation with the needles, a needle shield or guard forpreventing the thread'from a raised guide from engaging with the needlesat the knitting-point, and a carrier for said thread-guides andneedleshield movable so as to carry them away from `the cylinder inorder to permit of the removal of the same.
